They have mostly played TSR Basic D&D and BFRPG retro-clone adventures, which have similar amounts of magic; we are currently playing C&C adventure The Secret of Smugglers' Cove, a 3e conversion which has rather more I think. We've played weekly since March, roughly 8 months & something like 30-32 sessions. The first three PCs have been played up from 1st level; Roseanne joined more recently. I use death at -10, everyone has been 'mostly dead' at times, but no fatalities yet - though Raise Dead is available.
Bramble Hairyheals, Halfling-6: +1 platemail, +1 short bow, +1 short sword, 6 +1 arrows, 3 healing potions.
Claudia Morrigan, Thief-6: +1 leather, +2 dagger, +1 dagger, 3 healing potions, +2 ring of protection, continual light sapphire.
Alexandra Vorloi, Fighter-6: +1 sword, +2 ring of protection, +1 trident, 1 healing potion, 1 levitation potion.
Roseanne, Cleric-6: +1 platemail, +2 two-handed 'rune maul' warhammer (d8+2), 10 +1 sling bullets, 5 healing potions, scrolls: 2 cure light wounds, 1 bless, 1 raise dead.
I would not call them magic poor (eg I've been generous with healing potions), but the Classic assumption that +3 gear is more the kind of thing you start seeing around Name level differs quite a lot from my memories of AD&D play, I recall in my old AD&D games you'd be seeing +3 and +4 gear at level 6, generated by the 1e DMG treasure tables and often appearing in published 1e adventures.
Compared to AD&D, my Classic PCs average 1 hit point less per level, but I gave max hp at level 1 so that evens out. The Fighter types have slightly worse chances to hit, but most enemy ACs aren't great anyway. They don't get to attack 3 times per 2 rounds from level 7. No STR 18/00, but they typically have STR 16 for +2 attack & damage, better than AD&D STR 17 (+1/+1). Saves seem similar.
